Options

The Synchronet builds system supports a vast array of build options most of which are only slightly supported. This page attempts to document them for advanced users.

Supported Options

  • DEBUG
    • If defined, or if RELEASE is not defined, does a debug build.
  • FORTIFY
    • When combined with DEBUG, will build with _FORTIFY_SOURCE option (and enable basic optimization).
  • SANITIZE
    • When combined with DEBUG, will build with AddressSanitizer (ASan) and Undefined Behavior (UB) Sanitizer (not currently recommended/supported).
  • RELEASE
    • If defined, does a release build (no debug information).

    • Extra LDFLAGS for linking agsint JS
  • JSINCLUDE
    • Path to JS headers

    • Path to JS library.
  • JSLIB
    • Library name for SpiderMonkey.
  • EXTRA_JS_CONFIGURE_ARGS
    • Pass these arguments IN ADDITION TO THE BUILDIN ONES to the configure command when building the included SpiderMonkey.
    • Adding –disable-tracejit is commonly needed to build JS on less common OSs/Architectures. Please file a bug if it's required.
  • JS_CONFIGURE_ARGS
    • Pass to the configure command when building the included SpiderMonkey.

Other Options

  • SRC_ROOT
    • Overrides the path to the src directory. Normally set in the makefile.

  • USE_UPROFILE
